We have a customer that uses a snap server as storage for their SQL Server 2000 databases. Lately we've been getting issues creating the backups, especially on two of the very large databases (450 GB and 500 GB).
The error that I see (among others) is the following:
Operating system error 999(Error performing inpage operation.)
I haven't been able to find much explanation online regarding this error. The only two possibilities I've found are
1) Not enough disk space - I don't think this is the issue, it looks like there is plenty of space
2) Bad blocks on the drive - I don't know how to verify this.
